Answer 1

because laser is highly coherence and its angular spread is very small!

Answer 2

A laser beam is used for locating distint objects because the "laser is highly coherence" and "very small angular speed" is takes place.

Explanation:

• An enhanced process of stimulating the radiation that is electromagnetic and then optically amplify.
• It will produce the laser light, this light will always have a high coherent and consistent light that is monochromatic and hence will have an angular speed that is very small due to this coherent nature.
• It is normally used for locating objects that are placed at a distance because this light has the ability to travel so far.
